To all whom it may concern; y

Be it known thatI, JOSEPH E. CRISP, of Boston. in the county of ,Sui-folk, 111.tl1e 3 ri1A monwealtli of Massachusetts, have invented an Improvement in `Bo otf-Treeing Machines, 4of

` which the Afollowing is aspeciicatiou.

Thi-s invention relates to, boottreeinjg-,machines; and it` consists .indevices for t-reeingv the foot portion of .the boot, principallythat part infront of the side seams comprising vvhat is generallvcalled the s vamp.

Owing to the singular conformation offthe foot portion of the tree, .it is necessaryt'liat the` tool for smoothing 'and finishing the vamp thereon in the treeing A"process should be provided with a yieldingmovement and my yin-l vention relates to a yielding roll, which is provided `with a reciprocating movement from the toe to `or beyond the side seams, :and which traverses the entire upper@ surface of the Lfoot.

part ofV the `tree from one side to l theo'ther.`

It further relates to" means for automatically reversing the traversingmovem en t ot the tool,`

` so that `at any stated intervah preferably when thetoolhas reached "the" opposite side of the foot, the motion' is reversed, and the reciproeating and traversing movements are eontinued over the portionon which the tool has already acted. f

Reference is made to the accompanying drawings, formiu g `a part of thisspeci-flcation,I vin explaining the natureof my' invention, in

which Figure l is a side elevation'of my machine. Eig. 2 is a vertical section illustrating the construction of the tripping mechanism. Fig. 3 is a plan of the portion of the machine below the line w x of Fig. l. i l

The standard A supports a tree-holding device, a', adapted to be revolved horizontally, and furnished with any of the adjustments named inthe Patent No. 215,440, granted me May 20, 1879, and the boot is placed upon the boot-tree A', Withits sole resting against the support a', which is shaped upon the portion against which 4thesole of the boot or shoe contacts Ato conform to the curvature of the bottom or sole of the tree. This support projects upwardly from the bracket a2.

The roll B is supported upon the end of the spring-arm b, has a reciprocating movement parallel or substantially parallel to the sole,

yand to it the spring-arm b is fastene and is revolved by contact with the Work. 1t is provided With the reciprocating movement i by means of the shaft C, which :suitable bearing in the frame A, crank c`,"slo.tted lever c', pivoted" at c2 to the frame ofthe "machine, link c3, which connects the endlofthe lever "with the rod c, and `said rod cthasabearing in the revolving spur-Wheel D andA collar d, .j Any other ydesirable means for reciprccatjngthe yielding roll, however, may be fnnIQlOved.`

The `spur-Wheel D is provided Withabean ing in the bracket a?. The rodc1 hasagroove, d', intoV which the fast feather d2 `ontlie spurwheel projects, so that the rod,`and conseqnently the roll, revolves with the spupwheel.

The spur-Wheel is revolved successively inop posite directions by means of the Wormsd3 on the" shafts d4, which have suitable bearings in the frame E, and are revolved by meansof the driven pulleys e, belts e', and the `driving-pulleys e2 on the shaft C. The frame Eis pivoted at e3 to the bracket a2, and it is adapted to be inoved horizontally at the completion of the traversing movement of the rollbytlie spring` f2. Thelatch f and the catch f serveftohold the frame E stationary in relation to the spurwheel D until, upon the revolution of the spur- Wheel, the latch is tripped by onepof the inclined blocks f3. It will thus be seen that at the end of the traversing movementef the roll the frame E Vis automatically disconnected therefrom and moved suficientlyto engage the rever-sin g-worm with the spurwheel,there by effecting an automatic reversal of the traversin g movement of the roll. y

In operation the machine is so adj usted that the roll first operates upon the] section adjacent to the side edge from the 'toe to or beyond the side seam, upon either side, and by the slight traversing movement successive sections, substantially parallel with the first, are operated upon until the entire vamp to the sole-edge upon the opposite end has been subjected to the rolling action.A A A reverse movement is then produced automatically, if desired, and the operation continued,I the roll passing over the vamp from sole-edge to soleedge as many times as may be desirable for vamp.

It will be observed that by providing the roll with the traverse movement all portions of the vamp are reached, and that no portion is left untouched by the roll from the line upon which it commences to operate to the end of its movement, as the traverse movement is so slight that the' roll does not move laterally suficiently to leave any part of' the vamp uurolled between each reciprocation, but, to the contrary, overlaps sufficiently to break joints, as it were, between the section operated upon in its upward movement and that operated upon by its next downward movement.

The spring-arm should be shaped to provide a uniform stress upon the roll, and to yield or to give laterally to allow the roll to come to a proper bearing upon the surface of the tree, and this can be effected by making the springarm suiciently long and thin to allow it a slight torsional movement.

When itis desirable to tree shoes or brogans alast will be used instead of a boot-tree. A slight modification in the shape of the holding devices or jack will be necessary for supporting the last; but as there are a great lnauy contrivauces for jacking a last in a machine, it is not necessary to describe any1 specific construction.

I wish to state, however, that I intend that this mechanism shall be used for treeing shoes and brogans as well as boots, and that the adjustable roll herein described may be used upon any portion of the boot-tree in treeing the vamp or boot-leg. 4

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a machine for treeing boots and shoes, the combination of a boot tree or last, firmly supported within the machine, with a yielding roll or other smoothing and finishing tool, provided with a reciprocating movement and with an automat-ic traversing movement, substantially as and for the purposes described.

2. In a machine for treeing boots and shoes, the combination of a jack 0r last, irmly supported within the machine, with a yielding roll or other smoothing and finishing tool, provided with a reciprocating movement from the toe to or toward the heel, and with a traversing movement from one sole-edge to the' other, with the means for automatically reversing the traversing movement, whereby the roll is caused to automatically return over the surface previously rolled, substantially as and for the purposes described.

3. In a machine for treeing boots or shoes, the combination of a boot tree or last, firmly supported within the machine, with the roll B, spring-arm b, and the means for reciprocating the same upon the foot portion of the tree or last from the toe to or beyond the instep, the roll being revolved by contact with the vamp, substantially as and for the purposes described.

4. The combination, in a machine for treeing boots and shoes, of the boot tree or last firmly supported within the machine, the roll B, yielding arm`b, with means for reciprocating said roll and arm from the toe to or beyond the instep, and the means for providing said arm and roll with a traversing movement, substantially as and for the purposes described.

5. In a machine for treeing boots or shoes, the combination of the spur-wheel D, the reciprocating rod c4, the two worms cl3, and the means for automatically disengaging the drivin g-worm from the spur-wheel at the completion of a traverse movement, and for engaging the reversing-worm therewith, substantially as and for the purposes described.

6. In a machine for treeing boots and shoes, the combination of a boot tree or last with a smoothing and finishing roll, arranged and operated substantially asset forth, adapted to revolve automatically vby contact with the surface ofthe bootleg or upper upon the boot tree or last, whereby the boot leg` or upper is fitted thereto in the treeing process.
